Description
Technical field
The utility model relates to clothing arts involved in cold exchange device, specifically a kind of heat exchange tubing.
Background technology
In existing cold exchange device, the heat exchange tubing adopted mostly adopts structure as shown in Figure 1, be sleeved in outer pipe 1 by interior pipe 2, and ensure the axiality of two pipes, be welded and fixed by two ends, strengthen the rigidity of tubing, but now not only increase welding difficulty, and needing manual operations, amount of labour demanded is large, and cost is high.The tubing of independent inside and outside pipe 1,2 sleeve structure, owing to lacking support between two pipes, poor rigidity.
Also there is the difference in inner and outer pipe heat expansion space in the heat exchange tubing of pipe sleeve structure, in often existing, pipe heat expansion expansion space is not enough, easily causes cylindrical pipe explosion.
Utility model content
The purpose of this utility model is to provide a kind of heat exchange tubing, and it can, while enhancing tubing rigidity, not need to roll up labour's use amount, and this tubing can overcome that inner and outer pipes dilatancy difference causes split pipe problem.
The technical scheme in the invention for solving the technical problem is: a kind of heat exchange tubing, comprises outer tube and interior pipe; The lateral cross section ovalize of described outer tube; The lateral cross section of described interior pipe is cross, comprises outward extending four chamber arms centered by die; Described interior pipe to be coaxially nested with in described outer tube and four arm tops, chamber of described interior pipe respectively with the contact internal walls of described outer tube.The top outer wall of described interior pipe four chamber arms is arc, and the arc radius of the two chamber arms extended along elliptic focus direction on outer tube section is greater than the arc radius of perpendicular other two chamber arms.
Further, the arc-shaped transition connected structure for concaving between the adjacent two chamber arms of described interior pipe.
Further, described outer tube and described interior pipe are copper material pipe.
The beneficial effects of the utility model are: it, by changing the structure of inner and outer pipe, makes to form support therebetween, add the rigidity of gained tubing, eliminate simultaneously bring because of heat expansion difference between inner and outer tubes split pipe problem.

In figure: 1 outer pipe, pipe in 2,3 outer tubes, pipe in 4.
Detailed description of the invention
For ease of understanding technology contents of the present utility model, just by reference to the accompanying drawings technology contents of the present utility model is described further below.
As shown in Figure 2, a kind of heat exchange tubing, comprises outer tube 3 and interior pipe 4.The lateral cross section ovalize of described outer tube 3.The lateral cross section of described interior pipe 4 is cross, comprises outward extending four chamber arms centered by die.Described interior pipe 4 is coaxial and be nested with in described outer tube 3 with described outer tube 3, four arm tops, chamber of described interior pipe 3 contact with the arc inner wall of described outer tube 4 respectively.
In order to improve the conformability of interior pipe 4 and outer tube 3 contact position, when assembling for producing, interior pipe 4 is inserted in outer tube 3 and provide convenient, the top outer wall of described interior pipe 4 four chamber arms is all set to arc, in order to ensure interior pipe 4, the tight type coordinated between outer tube 3, pipe 4 in simultaneously coordinating, heat expansion sex differernce between outer tube 3, the arc radius of the two chamber arms (about symmetrically arranged two the long chamber arms of vertical plane) extended along elliptic focus direction on outer tube 3 cross section is made to be greater than the arc radius of perpendicular other two chamber arms (about symmetrically arranged two the short cavity arms of horizontal plane), namely the arcuate structure of long chamber arm and elliptic focus to two ends adapt, forming surface contact coordinates, the arcuate structure of short cavity arm forms linear contact lay with the other two ends of ellipse and coordinates.Distortion focussing direction when making interior pipe 4 heat expansion like this and the distortion focussing direction (focus direction) of oval outer tube 3 basically identical, pipe 4 in reducing, outer tube 3 contact position distortion residual quantity, and because of interior pipe 4, larger cavity structure is there is between outer tube 3, so have the characteristic of easily taking refuge that becomes for interior pipe 4 self, namely during heat expansion, the deflection of interior pipe 4 each several part on respective deformation direction is inconsistent, this is just different from the basically identical flat characteristic of the next position of pipe heat expansion deflection in all directions completely, so decussate texture makes interior pipe 4 have certain self-control in heat expansion distortion, thus improve the heat expansion of self.
For reducing the problem of stress concentration between adjacent chambers arm that interior pipe 4 structure causes because of decussate texture, the arc-shaped transition connected structure for concaving between the adjacent two chamber arms making described interior pipe 4.
In most cases, the material of heat exchanger tube is red copper, so described outer tube 3 in the utility model and described interior pipe 4 also all can be red copper material pipe.
The utility model is by changing the structure of inner and outer pipe, make to form support therebetween, add the rigidity of gained tubing, simultaneously make interior pipe 4 in cross with regard to structure after, the expansion space of interior pipe 4 can become large, the interval that the heat expansion difference of itself and outer tube 3 allows increases, and arc-shaped transition creates between buffering area for its self-control, because of this eliminate bring because of heat expansion difference between interior pipe 4 and outer tube 3 split pipe problem.
Except the technical characteristic described in description, be the known technology of those skilled in the art.
